LOCKING ACTUATOR STEM AND ROD END BEARING APPARATUS FOR USE WITH FLUID VALVES |
摘要 |
<p>Actuator stem (204) and rod end bearings (210) having locking mechanisms are described. An example apparatus for use with a control valve actuator includes a rod end bearing having a bearing retainer and a shaft portion extending from the bearing retainer. The apparatus also includes an actuator stem having a first end to be operatively coupled to a diaphragm plate (108) of the control valve actuator and a second end to be coupled to the rod end bearing. A locking mechanism coupled to the actuator stem or the rod end bearing prevents the actuator stem and the rod end bearing from decoupling when the actuator stem is coupled or de-coupled to the diaphragm plate.</p> |
